"Not only did they come on the appointment date, they called and due to a cancellation asked if they could arrive earlier. The dryer vent was cleaned and the dryer no longer shows an overheating code. Great job. Will definitely call them again if needed and will have air ducts cleaned as well."

Air Duct Cleaning questions, answered by experts

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

It is generally not a good idea to completely cover or close air vents. While you might have heard that closing vents in unused rooms saves energy, it does not improve HVAC performance or lower your energy bills. In fact, blocking, covering, or fully closing vents can create a buildup of pressure inside your ducts, which can lead to leaks, holes, or other problems. To maintain proper airflow, you should also avoid covering vents with furniture. If you want to reduce airflow to unoccupied parts of your home, it is better to partially shut the vents (between 50% and 75%) rather than closing them completely.

The best air duct cleaning methods involve removing the debris or dust in the ductwork through the use of a vacuum. Air duct pros refer to this method as negative pressure cleaning. To knock debris loose inside the ductwork, you may need to use a hand-operated brush or a rotary brush. You then can use the vacuum to suck up the loose debris and remove them from the ducts. If mold is present, pros may use a chemical spray to try to kill any bacteria or mold inside the system.

Mold in HVAC ducts is a relatively common issue that homeowners struggle with—especially in humid climates or homes with poor ventilation. Moisture from condensation, combined with dust and organic debris, creates the perfect environment for mold growth. Homes with high humidity, leaky ducts, or clogged drains are more prone to this issue. Regular inspections and proper HVAC maintenance significantly reduce the risk of mold developing in your ducts.

If you have a fresh air intake as part of your HVAC system, the interior vents should be near your furnace or other gas appliances inside your home. From the outside of your property, your HVAC fresh air intake location is usually near the ground (although it may also be higher up, like on the roof or attic).
